More difficult than the last few weeks. As with this type of puzzle
it is a question of deciding which clues contain the jumble.
After dusting off my Brewer I felt a bit of a prune for taking so long
to get the phrase and the connected unclued lights.
Enjoyable.
Thanks for the link and an excellent challenge, best we've seen for a while. The scales, so to speak, might have been slightly more evenly tilted towards the second part of the phrase, but that's nitpicking.
Thanks for the link, Mintyman. After two relatively easy weeks, this one is much more of a challenge. I have managed to get it all except 14A, which is proving to be a tough nut to crack.
With the grid otherwise complete & despite the hints above I still can't see what any of the (limited) possible solutions to 8A & 6D have to do with either theme.
What am I missing?
(Besides the relevant brain cell that is!)
